Image Number 19 - Artery, carotid, arteriosclerosis obliterans

Note the occluded left carotid artery that is highlighted by arrow #1. Compare the occluded lumen of the left carotid artery with the patent right carotid artery seen at arrow #4. Arrow 2 indicates the left vertebral artery as it lies on the ventral surface of the medulla. The junction of the vertebral arteries to form the basilar artery is seen at arrow #3. Atherosclerosis is a type of arteriosclerosis. It is important to understand the following terms with respect to the gross and histological appearance and the genesis of each of these pathological conditions: fatty streak, atheroma, complicated plaque, arteriolosclerosis, and Monckeberg's arteriosclerosis.
